To all whom it may concern:

Be it known that I, Fnrrmor GUSTAF ERICSON, a subject of Great Britain,of the city of Toronto, in the county of York, in the Province ofOntario, Canada have invented certain new and' useful Improvements inLanding-Gear Construction of Aeroplanes, of which the following is thespecificatio My invention relates to improvements in landing gearconstruction of aeroplanes and the ob ect of the invention is tosimplify the construction of the connecting means between the front'andrear struts of the landing gear and yet provide such .a means as will berigid, strong and durable and at the same time cheap and readilyconstructed and it consists essentiallyof the following arrangement andconstruction of parts as [landing gear showing my connection be-.

hereinafter more particularly explained.

Figure 1, is a sectional view through a tween the front and rear struts.

Fig. 2, is an end, elevation of theparts shown in. Fig. 1.

Fig. 3, is an enlarged perspective detail of the connecting means betwten the front and rear struts.

Fig. 4 is a perspective view of the block to which the knee platesare'isecured; the

knee plates being shown in dotted lines.

In the drawings like lettersof reference indicate corresponding parts inthe various figures.

1 indicates a vided with the usual axle 2. 3 and 4 indicate the strutsof the landing gear.- Heretofore the lower ends of these struts havebeen connected together by a single bracket which is complexinconstruction,-expensive and diflicult to make. In order to dispense withthis bracket and cheapen and simplify the construction I have providedthe follow-- ing device.

plates, which are suitabl secured at each side of the block 5 by bo ts 8which extend through the plates 6 and 7 and through the block 5. Theends of the plates 6 and 7 are bent in any suitable manner to conform tothe shape of t e knee block 5 so as to conform to the ection of thestruts 3 and 4 and are extended beyond the ends of the knee blocks toform sockets into which the ends of the struts 3 and 4 extend forming abutt joint with each end of the knee block 5. The struts are secured inposition by bolts 9 and 9", which extend through the plates 6 and 7 andthrough the ends of the struts 3 and 4 intervening between the extendedends of the plates 6 and 7.

From this description it will be seen that I have devised a simpledevice by which the front and rear struts of an aeroplane landing gearmay be securely connected together dispensing with all complex bracketsand merely employing a block and side plates of very simple and cheapconstruction.

What I claim as my invention is.

In combination with the downwardly converging front and rear struts ofan aeroplane landing gear, a block having a knee form providing portionsu wardly diverging from near the center 0 the block, said portionshaving their end faces inclined and convergent upwardly to form buttjoints with the ends ,of the struts, plates extending along the sides ofthe block and beyond the same with means for securing said plates to theblock and to the ends of the struts, sub stantially as described.
